Comparative Plots

For each of several sets of example signals with noted signal-to-noise ratios, we see the rectangular window models in the first subplot and the Hann window models in the second subplot. As expected, the magnitude inversion model discussed above reaches an asymptotic value corresponding to the width of the window transform. We also see the empirical effect of the minimum $\alpha $ requirements mentioned repeatedly above.
